BRAKE-BEAM FULCRUM.

SPECIFICATION forming part of Letters Patent No. 781,545, dated January 31, 1905;

application filed May z, 1901.1. serial No. 206,018.

T all whom, t may concern: i A Be itknown that I, JOHN F. OCoNNoR, a citizen of the United States, residing at Easton,-

Pennsylvania, have invented certain Improvements 1n Brake-Beam Fulcrums, of lwhich the following is a specification. i

The object of my invention is to provide a two-part fulcrum for a brake-beam in which the two parts are preferably identical and which can be held rigidly by a pin and a singlc rivet. This object I attain in the following manner, reference being had to the accompanying drawings, in which` Figure 1 is a side view of my improved fulcrum applied to a brake-beam, the beam being' in section. Fig. 2 is an end view. Fig. 3 isa section on the line 3 3, Fig. 2. Fig. 4 is a section on the line i 4., Fig. 2. Fig is a section on the line 5 5, Figfi. Fig. 6 is a perspective view of` one of the parts of.. the fulcrum. Fig. 7 is a perspective View of the pin, andFig.' 8. is a viewvshowing the coupbody portion is an arm d, perforated at d' for the passage of the fulcrum-pin, to which the brake-lever is pivoted, the leverV iittingbetween the two arms dd. The arms are arranged at an angle to the body portion, as shown, to accommodate the brake-lever.` It will be noticed that the bodyportion of each part is cut away at b, so that the projecting lportion [fof one part will fit in the recess b of the other part, as clearly shown in Fig. 2, and in each portion b2 is a cavity 'e for the reception ofthe coupling-pin E, one half of the pin extending into the cavity of one part, B, and the other half of thepin extending into the cavity in the other part,.B, and arranged 'parallel with the beam. The cavities may be arranged at a slight angle, as shown in Fig. 8, so that when the two parts are coupled the angle of the pin will tend to draw them close together. It will be noticed that the cavities e e are closed by a wall e at the outer end, so that when the parts are together the pin is prevented from moving longitudinally and is thus held in position. The pin E is shown circular in the present instance; but it will be understood that the pin and cavities c e may be any shape desired. In some instances the pin E may be rigidly attached to onev part and loose in the other without departing from my invention. A

To apply the fulcrum to the beam, the two parts are placed one onv one side of the beam and the other onfthe opposite side, the pin is placed in one cavity, and the two parts drawn together, causing the pin to enter the other cavity. Vlhen thel two parts are close to'- gether and in position, a rivet c is passed through( the openings in the body portions and beam and headed, thus securing the ful- -crum rigidly to the 'beam with but a single parts' and extending parallel to the brake- Y beam, and means for securing the two parts to the beam, substantially as described.

3. The combination'in a brake-beam fulcrum, of two parts,'each having'a body portion and an arm, a cavity in each part closed at the outer end and a pin mounted in the cavity, substantially as described.

4. The combination ina brake-beam fulcrum, of two parts, each part having a body --portionarranged to fit around a flange of a oted, each part having a cavity closed at the outer end and a pin mounted in the cavities and coupling the t\vo parts, substantially asv described.

5. The combination in a brake-beam fulcrum, of tWo similar parts, each having a body portion and an arm, the body portion of one part having a projection fitting a recess in the body portion of the other part, a cavity in each projection closed at one end and a pin mounted in the cavities, substantially as A described.

6. The combination in a brake-beam fulcrum, of two parts, :t body portion :md :in :irni forming each part, a cavity in euch pau-t :xr- I 5 ranged at an angle and closed at one end, :md a, pin mounted within the cavities,substantial ly as described.

In testimony whereofl I have signed my name to this speciicntion in the presence of two sub- 2O scribing;l witnesses.

JOHN F. OCQNNOR.
